Types

type DataType

type DataType int

DataType signifies the data type of the field.

const (
	// BasicArray represents a simple array type for a field.
	BasicArray DataType = iota
	// CompositeArray represents a variable length array with
	// a non primitive type.
	CompositeArray
	// CompressedArray represents a variable length array which
	// can pack multiple elements into a leaf of the underlying
	// trie.
	CompressedArray
)

List of current data types the state supports.

type FieldIndex

type FieldIndex int

FieldIndex represents the relevant field position in the state struct for a field.

const (
	GenesisTime FieldIndex = iota
	GenesisValidatorsRoot
	Slot
	Fork
	LatestBlockHeader
	BlockRoots
	StateRoots
	HistoricalRoots
	Eth1Data
	Eth1DataVotes
	Eth1DepositIndex
	Validators
	Balances

	NextSyncCommittee
	LatestExecutionPayloadHeader

	LatestExecutionPayloadHeaderDeneb
	NextWithdrawalIndex
	NextWithdrawalValidatorIndex
	HistoricalSummaries
)

Below we define a set of useful enum values for the field indices of the beacon state. For example, genesisTime is the 0th field of the beacon state. This is helpful when we are updating the Merkle branches up the trie representation of the beacon state. The below field indexes correspond to the state.

func (FieldIndex) ElemsInChunk

func (f FieldIndex) ElemsInChunk() (uint64, error)

ElemsInChunk returns the number of elements in the chunk (number of elements that are able to be packed).

func (FieldIndex) RealPosition

func (f FieldIndex) RealPosition() int

RealPosition denotes the position of the field in the beacon state. The value might differ for different state versions.

func (FieldIndex) String

func (f FieldIndex) String() string

String returns the name of the field index.
